Definitions

  • the present invention relates generally to construction hardware, and more particularly to an improved fastener apparatus for metal roofing and steel building construction.
  • Fasteners for use in roofing and steel building construction presently include the ring shank, self- sealing nail and the self-sealing hex head. Manufacturers of these fasteners recommend replacement of the installed fasteners every five years . This recommended replacement schedule is necessitated by damage to the exposed rubber seals used for these fasteners by ultraviolet rays. Additionally, the gravitational shearing forces of ice and snow on roofing surfaces employing the hex head builds up against the hex head vertical walls, loosening the fasteners and causing damage to the fasteners and their seals.
  • U.S. Patent No. 6,764,262 discloses and claims a weatherproof fastener comprising a shank and head, wherein the head further comprises a recessed lower surface.
  • a gasket is positioned in the recess and, as the fastener is employed to join two elements, the gasket is compressed to entirely fill the recess to prevent ingress of undesirable materials.
  • the 6,764,262 patent fails to address or protect situations where the fastener is applied at any off angle other than ninety degrees, since the solid connection between the shank and the head create a solid "T" shape. When the fastener of the 6,764,262 patent is applied at an off angle, one head side contacts the workpiece while the opposing head side rises up creating a gap between the workpiece and the head outer rim. This gap provides ingress of undesirable materials to the head underside, and eventual fastener failure .
  • the present invention provides an improved fastener apparatus for use in roofing and steel building construction.
  • the inventive fastener provides a self- adjusting and automatically self-leveling head which is separate from the threaded shank portion.
  • This self- leveling head provides a frusto-hemispherical head, a curved outer surface, a base, a peripheral edge, and a rounded annular cup center.
  • the rounded annular cup center is wider and having near vertical sides at the uppermost portion, and curves and narrows towards a nearly horizontal surface at the lower portion.
  • the cup center is sized and designed to receive a separate threaded shank inserted through the separate head.
  • the threaded shank has threads leading to a threadless tip at one end and a rounded ball shank at the other end, and a flat top surface bearing a tool fitting.
  • the combined annular cup head and rounded ball shank create a free moving ball joint which allows the free moving head to self level under compression of installation regardless of the angle of installation of the threaded shank.
  • the head has a downwardly-appending lip which extends from the head peripheral edge, thus defining an annular recess in the base.
  • the annular recess comprises a flat upper surface which transitions to a vertically downwardly-appending lip.
  • the vertically downwardly-appending lip transitions into an annular wall at approximately 100- to 110-degrees to the horizontal, and ends in a curved lowermost bottom of the annular lip.
  • the bottom of the lip is substantially flat and transfers into an upwardly-appending peripheral edge sloping outwardly at approximately 110 degrees from the horizontal, and then transfers into the frusto- hemispherical head.
  • the recesses and downwardly appending lip are sized to receive a sealing gasket which seats around the threadless top of the shank to create a water tight seal.
  • the self-leveling head prevents the fastener head perimeter and downwardly-appending lip from scratching a painted workpiece during installation.
  • the sealing gasket contacts the workpiece as it is being fastened and begins to compress and provide resistence. In this manner, the remaining uncompressed portion of the gasket seal contacts the workpiece and adjusts the free-moving head to a level position before final compression of the gasket seal occurs, resulting in a final fastener head position that is flush with the workpiece, yet level to the horizontal plane.
  • a second thin sealing gasket is also inserted between the rounded ball head of the shank and the rounded cup of the free-moving head recess. This second seal gasket provides a barrier between the ball and cup to prevent rusting or electrolysis and to stop any ingress of water into the recess.
  • the separate heads of the fastener combine to provide one low profile head to reduce friction between the fastener and unloading snow and ice which can shear the fastener head and tear the entire fastener from an installed position.
  • the lip has six specific features. First, on the lip inside surface, the top twenty percent of the annular recess is vertical in order to catch the top surface of the seal gasket and prevent it from expanding horizontally, thus increasing resistance between the seal gasket and the workpiece to self-level the fastener head. Second, seventy percent of the annular recess wall transitions into a 110 degree sloping wall which widens as it nears the lip bottom, thus allowing the seal gasket to slowly expand and fill the recess. Third, the final ten percent of the annular recess is rounded so that the seal gasket escaping the recess and extending under the lip is not pinched or cut by the inside surface of the recess wall.
  • the bottom-most lip surface is substantially flat and wide to accommodate a portion of the seal gasket and to create a scratch barrier between the lip and the workpiece being fastened.
  • the bottommost lip surface transitions into a rounded portion which removes any sharp edges that might scratch the workpiece being fastened.
  • the outer peripheral edge slopes up towards the main body of the fastener head at a 110 degree angle.
  • This section creates a horizontal V-shaped cavity which accommodates the excess seal gasket that escapes from the recess to be protected from unloading snow and ice as it resides within the horizontal V-shape created between the workpiece and the peripheral edge at a 110 degree angle of the edge.
  • the recessed lip works in unison with the seal gasket, the workpiece, and the free moving head of the fastener to self-level the head portion regardless of the angle the threaded shank is installed.
  • the seal gasket within the annular recess first makes contact with the workpiece and is sandwiched between the free moving head and the workpiece being fastened.
  • the seal gasket is slightly compressed and begins to expand outwardly in a horizontal plane.
  • the short top twenty percent vertical wall of the lip is sized to stop the outward expansion of the seal gasket as the seal contacts the vertical recess wall.
  • the seal gasket contact with the vertical wall also creates immediate and increased resistance from the seal which causes the free moving head to self-level. Once the free moving head has self-leveled, the lowermost portion of the seal gasket is allowed to gradually expand along the angled 110 degree mid portion and fill the remaining recess.
  • the extreme bottommost portion of the inner recess wall is rounded and will not damage the seal gasket as it expands at an acceptable rate for the composition of the seal, eventually escaping from the recess and providing a scratch barrier between the fastener head lip and the workpiece being fastened.
  • the substantially flat and wide bottom surface of the lip is designed to accommodate the escaping seal and further aid in the self-leveling of the free moving head and provide a scratch barrier between the lip and the workpiece.
  • the final portion of the downwardly-appending lip is the peripheral edge designed at a 110 degree outward angle to accommodate a small amount of seal gasket which may completely escape from the recess and even beyond the lip portion of the recess to stop the ingress of undesirable materials and water.
  • the separation of the threaded shank portion with a rounded ball head and the head portion with rounded cup combine and create a ball joint which allows the threaded shank portion to spin during installation while the free moving head portion is held by the installer without the head portion spinning in the installer's fingers. Further, as the head and seal gasket make contact with the workpiece being fastened, the seal gasket contained inside the recess is not subjected to extreme twisting and binding which would damage the seal gasket during installation.

  • the free moving head 75 comprises a frusto- hemispherical head 5, a hollow center formed in a rounded cup shape 4, a flat base 17, and a peripheral edge 16.
  • a downwardly-appending lip 30 extends from the peripheral edge 16 and defines an annular recess 40 in the base 17, Figs. 4 and 5.

  • the threaded shank 50 and the free moving head 75 combine to create a ball joint to allow the fastener to self-level the head regardless of the angle the shank 50 is installed off vertical, Figs. 3 - 6.
  • the ball 3 on the head 80 bottom of the shank 50 combines with the cup 4 of the free-moving head 75 and provides a durable head that rotates to any position up to 30-degrees off vertical. This rotational freedom allows the free-moving head 75 to self-level under the compression of installation.

In this fashion, rusting and electrolysis of the assembled and installed fastener are prevented, as is the ingress of water into the annular recess 40 through the ball 3 and cup 4.
  • the preferred embodiment of the seal 6 is made from nylon or rubber.
  • the head 80 of the threaded shank is rounded or convex 1, Fig 4.
  • the free-moving head 75 external top surface is also convex and low profile to reduce friction between unloading snow and ice and the fastener head to reduce head shear.
  • the annular recess 40 is designed to accommodate a seal gasket 7 that, when in an uncompressed state, filles the recess from the threaded shank 9 to the vertical wall 12 of the annular recess 40 downwardly-appending lip 30. Under compression, the vertical wall 12 stops the top portion of the seal gasket 7 from expanding laterally from center and causes the seal gasket to compress and close towards the center and seat around the un-threaded top length 8 of the shank 50.
  • the preferred embodiment of the seal gasket 7 is rubber.
  • the annular mid portion of the recessed wall 13 is at an angle of 110 degrees from the vertical wall, and allows the lower portion of the seal gasket 7 to compress and transition from the inward motion towards the top of the seal to a gradual outward motion along the annular mid portion of the recessed wall 13 of the downwardly- appending lip 30, Figs. 4 and 5.
  • This design compresses the seal gasket 7 around the smooth upper shank surface 8 to prevent ingress of water through the ball 3 on the head 80 bottom of the shank 50 and the cup 4 of the free- moving head 75 into the annular recess 40.
  • the lowermost inner edge 14 of the downwardly- appending lip 30 is rounded so the free moving-head 75 has no sharp edges and does not cut or pinch the seal gasket 7 during installation, Figs. 4, 5, and 7A - 7C.
